No Calendar Events Displaying In Frontend

Good day,

Since upgrading JEvents to version 3.4.33 no events created are displaying in either the Calendar or Upcoming Events modules. This remains an issue whether it is a multi-day or single day event; whether the event is past, present or future.

Component and module settings are identical between the live site and a backup running an earlier version of JEvents. All events, calendars and categories are published with access level set to public.

Help needed! Cannot think of what to check or try next.
